Engine Components

In the field of diesel engine components, ceramic glow plugs assisting quick start up of chamber diesel engines had been developed in September, 1981 and ceramic swirl chambers followed in commercialization in April, 1983. These ceramic components are currently under commercial production and are installed on passenger cars on the merket. Silicon nitride (Si3N4) is the material of these components, and a lot of mass-production technique has firmly established in order to achieve competitive price and high durability in comparison with the conventional metal components. Because of its excellent heating characteristics, ceramic glow plugs have eliminated the “waiting time” before the start-up of diesel engines. As the result, drivers can enjoy quick starting of engines as they can do with gasoline fueled vehicles. Ceramic swirl chambers could drastically reduce idling noise of diesel engines and remarkably improved starting performance in the cold climate operation.

Low Speeds

Turbocharged passenger cars have been in use more than three decades. However, the behavior of the engine at low engine speeds is still unsatisfactory. Experimental work has been carried out on turbochargers aiming to improve the behavior of the engine at low speeds. For this purpose a turbine with adjustable guide vanes has been designed and tested. These experiments were done on a turbocharged 31 diesel engine from Daimler-Benz. Three different turbine nozzle blades have been designed and tested without using a waste gate. The results are compared with those of the Garrett-turbocharger T03 which was originally installed with the engine.

According to the title, the article compares passenger cars produced in versions with SIE engines (spark ignition engines) and CIE engines (compression ignition engines), taking into account the situation on the Polish automotive market. A group of 25 selected vehicle pairs equipped with the SIE and CIE engine versions has been presented. The measurable comparative criteria have been defined. The results of the comparison were presented in the form of graphs with a commentary. The situation on the Polish automotive market was also assessed in the context of a comparison of both types of vehicles. The final conclusions close the article.

Engine Reliability

Globally, the transport sector consumes the biggest share of the fuel supply. Common fuels used in the transport sector are petrol and diesel. Diesel engines have been proven to be more advantageous over gasoline engines, in the aspects of fuel efficiency and engine reliability. The use of diesel passenger cars is very popular in European countries compared to Malaysia. A wider use of diesel-powered cars in Malaysia may benefit the car users, government and the country. The study of the causes of the low percentage of diesel-powered car usage in Malaysia was examined in this present study by using the latest data available in the literature, and by conducting a survey to measure the perceptions and views of the Malaysian public towards diesel-powered passenger cars. Results of this study showed that most of the respondents admitted that diesel engines give more savings. However, respondent perception that diesel-powered cars emit noise and high air pollution of the environment is the main reason Malaysians not choosing diesel-powered cars.

Noise Evaluation

The noise of diesel engines operating at low idle is an important noise evaluation criterion in both commercial vehicles and passenger cars. At low idle, a quiet, pleasant noise is required. Therefore, any unusual noises that occur at low idle represent a serious problem, and the noises must be prevented. This paper presents the characteristics of the moan noise, which is an unusual noise that radiates from the oilpan at low idle, and the mechanism by which the moan noises are generated in a diesel engine. In addition, a means of preventing the moan noises is discussed.

Ambient Temperatures

Spark-ignition (SI) engines are highly susceptible to excess emissions when started at low ambient temperatures, a phenomenon which has been widely discussed in the literature. Direct injection diesel engines feature a markedly different fuelling and combustion strategy, and as such their emissions behaviour is somewhat different from gasoline engines. The excess emissions of diesel engines at low ambient temperatures should also differ. The aim of this study was to compare excess emissions of gaseous and solid pollutants over a legislative driving cycle (the New European Driving Cycle, NEDC) following cold start at a low ambient temperature for both engine types. This paper examines emissions at low ambient temperatures with a special focus on cold start; emissions are also compared to start-up at a higher ambient temperature (24 °C). The causes of excess emissions andfuel consumption are briefly discussed. A series of tests were performed on European Euro 5 passenger cars on a chassis dynamometer within an advanced climate-controlled test laboratory at BOSMAL Automotive Research and Development Institute, Poland. Emissions data obtained over the Urban Driving Cycle by testing at 24 °C and at -7 °C, are presentedfor a selection ofmodern Euro 5 gasoline and diesel vehicles representative of the European passenger carfleet. A full modal emissions analysis was also conducted at 24 °C and at -7 °C over the NEDC. Emissions andfuel consumption were substantially higher at -7 °C than at 24 °C.
